Class Name

For users who have SAP2000 installed on the computer, this model allows parameters to be given to SAP2000 and results to be returned to Rt.

Allowable characters are upper-case and lower-case letters, numbers, and underscore (“_”).
The name is unique and case-sensitive.

C:/Program Files/Computers and Structures/SAP2000 14/SAP2000.exe

Absolute path to the location of the SAP2000 inputfile. Note that the file with $2k format has to be used as the input file, for example:

C:/Input.$2k

This model does not automatically create any response objects.
Rather, create File Response objects.
In those objects, specify the name of the SAP2000 and the name of the file where SAP2000 puts the response.

To etablish a functioning connection between SAP2000 and Rtx and use its results in Rt, the following procedure could be followed:
It is recommended that the output files of SAP2000 are saved in the same directory as Rt's executive file.
Make sure that the $2k file has to be registered as the input file
Properties of the SAP2000 object has to be filled as it has been described in the properties section.
List of random variables also has to be defined. Note that these variables have to have a consistent naming as the ones in the SAP2000 object
To extract the results and use them in Rtx analyses, one can create a Database Response like this:

You can check Database Response for further information on how to fill out the properties section.

Finally, a proper Limit State Function should be defined to evaluate failure probability and reliability index, using SAP2000 results:
Before running the analyses, it is recommended to check whether Rtx and SAP2000 are well-connected, using Function Evaluation Analyzer.
